The Medical Corps has historically had a 100% promotion opportunity for O4/LCDR, but the 2020 NDAA limits promotion opportunities to 95%:
I have no insight into why this change was made, and would only be guessing, so I won’t bother. How would this have affected our most recent FY20 board?
The FY20 O4 board had 253 LTs in-zone and a 100% promotion opportunity for O4, therefore they were allowed to pick 253 LTs total from those in-zone, below-zone, and above-zone. Here’s how it broke down:
As you can see, they picked 253 (6 + 223 + 18).
If you apply a 95% promotion opportunity, they would have only been able to pick 240 (253 x 95%), so 13 people would have lost out.
Whether this will lead to less below-zone picks or what other effects it will have we’ll just have to see.
